To all whom it may concern: 7

Be it known that I, EDWARD J. FISH, a citizen of the United States,residin at Lowville, in the county of Lewis and tate of New York, haveinvented certain new and useful Improvements in Devices for Taking OutDents in Milk-Cans; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompany, ing drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to new and useful improvements in devices fortaking out dents, creases, etc., in milk cans and other receptacles, andcomprises a simple and efiicient apparatus 0 this nature having variousdetails of construction and combinations and arrangements of parts whichwill be hereinafter fully described, shown in the accompanying drawingsand then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a vertical central sectional view through my improveddevice. Fig. 2 is a cross sectional View through the same, and Fig. 3 isa detail perspective view.

Reference now being had to the details of the drawings by letter,A.designates a plate which is concaved upon its upper surface andadapted to form a support for a can B having a bottom to conform to andcontact with said concaved part. A disk C is convexed upon its lowersurface and is adapted to rest upon the concaved bottom of the can towhich the device is to be applied, and a screw D has its lower endswiveled in a central opening formed in said disk C and its upper endhas an operating wheel E fixed thereto. A block F has a threaded openingtherein for the reception of said screw and the ends of said block areslotted as at F, and pins H pass through registering apertures in thewalls of said slots and upon these the inner ends of the links I areivotally mounted, their outer ends being plvotally mounted upon the pinsJ which pass through registering apertures in the walls of the slottedlugs N which project from the inner concaved surfaces 5 of the formersor swage blocks 0. Said blocks 0 have their upper portions tapering asshown and each is of semi-cylindrical ships and hollow and their outerconvexed su aces are adapted to conform to. the.wall of the can andtheir upper tapering portions to the tapering part of the can in whichthey are to be utilized for the purpose of taking out indentures,creases or other irregularities in the wall of the can.

A second block, designated by letter M,

is threaded upon the screw above the block F and has slotted ends M andthe upper surface of said block M is concaved transversely as at Q, forthe race tion of the plates R which are convexe upon their ower surfacesand concaved upon their upper surfaces, and each is provided with atransverse slot R which is in registration centrally with the slot M.Link chains T are fastened each at its lower end to an eye W fastened tothe inner surface 'of the former blocks 0 and said links are adapted toengage the slots R formed in the plates which areseated in the recessesin the upper surface of the block M, said chains being provided for thepurpose of holdin the two former blocks 0 in different ad ustedpositions according to the size of the can which they are to operateupon in taking out the dents in the wall thereof.

In operation, the can is placed upon theconcaved plate A with theconvexed bottom of the canconforming to'the dished upper surface of saidplate and the disk which is swiveled to the lower end of the screw isplaced within the can and its lower tapering surface conforming to theconcaved, bottom of the can. By this arrangement, it will be noted thatthe shape of the bottom of the can Will be maintained by reason of thedisk and plate both conforming to the bottom thereof, thus allowing thebottom Patented July 23, 1912. v

to withstand the necessary pressure which 1 might come upon it in theoperations of the apparatus. The former blocks are adjusted to conformto the size of the can by spreading the same in opposite directions bypulling up upon the chains and, after being adjusted properly, the linksof the chains are caught in the slots of the plates R, thus maintainingthe bottoms in their adjusted positions, after which the operator byturning the hand wheel, may cause the blocks F and M to be raised andthe convexed portions of the former blocks be made to be drawnfrictionally against the uneven surfaces of the can, thus tending tostraighten out any irregularities therein. The former to further assistin straightening out irregu-v larities. After the dents have beenremoved from the cam-the screw may be turned in the reverse directionand the chains released from their plates and the forming apparatusremoved from the can.

What I claim to be new is 1. A device for removing-dents and creasesfrom milk cans, consisting of a disk adapted to rest upon the bottom ofthe can, a screw swiveled to said disk, means for turning the screw, ablock having threaded connection with the screw, expanding members withpivotal link connections between the same and said block, and means forholding the expanding members in different relative positions to conformto different diameters of cans, as set forth.

2. A device for removing dents and creases from milk cans, consisting ofa disk adapted to rest upon the bottom of the can, a screw swiveled tosaid disk, means for turning the screw, a block having threadedconnection with the screw, expanding members with pivotal linkconnections between the same and said block, a second threaded blockupon said screw, and adjustable means connecting the same with saidexpanding members, as set forth.

3. A device for removing dents and creases from milk cans, consisting ofa disk adapted to rest upon the bottom of the can, a screw swiveled tosaid disk, means for turning the screw, a block havin threadedconnection with the screw, expan ing members with pivotal linkconnections betweenthe same and said block, a second threaded. blockupon said screw, and chains fastened each to one of said expandingmembers and adapted to adjustably engage said swiveled block, as setforth.

4; A device for removing dents and creases from milk cans, consisting ofa disk adapted to rest upon the bottom of the can, a screw swiveled tosaid disk, means for turning the screw, a block having threadedconnection with the screw, expanding members with pivotal linkconnections between the same and said block, a second threaded blockmounted upon said screw and having slotted ends, chains fastened one toeach of said expanding members and adapted to engage the slots of saidswiveled block to hold the expanding members in adjusted positions, asset forth.

, 5. A device for removing dents and creases from milk cans, consistingof a disk adapted to rest upon the bottom of the can, a screw swiveledtosaid disk, means for turning the screw, a block having threadedconnection with the screw, expanding members with pivotal linkconnections between the same and said block, a second threaded blockmounted upon said screw and having slotted ends, slotted plates fastenedto the upper surface of the second threaded block and over the slottedends thereof, and chains fastened one to each of said e'xpanding membersand adapted to' engage the slotted plates, as set forth.

6. A device for removing dents and creases from milk cans, consisting ofa disk adapted to rest upon the bottom of the can, a screw swiveled tosaid disk, means for turning the screw, a block having threadedconnection with the screw, expanding members with pivotal linkconnections between the same and said block, a second threaded blockmounted upon said screw and having slotted ends, the upper surface ofsaid second threaded block having transverse concaved recesses formedtherein, plates convexed upon their under surfaces and engaging saidrecesses and each slotted in its edge, link chains fastened each to oneof said expand ing members and adapted to adjustably ene gage saidslotted plates, as set forth.

7. A device for removing dents and creases from milk cans, comprising aplate with its upper surface convexed to conform to the concaved bottomof a can and adapted to rest thereon, a disk adapted to rest upon thebottom of th can, a screw swiveled to said disk, means or turning thescrew, a block
